Uragasaurus is known from just one well-preserved backbone bone from the front of the back, called an anterior dorsal vertebra.1
The backbone had a Y-shaped pattern of bony ridges that is unique to this dinosaur.1
CT scans showed that the inside of the backbone was filled with tiny air spaces, a feature called camellate structure, which made the skeleton lighter.1
Uragasaurus lived during the latest Jurassic period, about 149 to 137 million years ago.4
It belongs to a group called Mamenchisauridae, which were famous for their extremely long necks.1
This dinosaur was discovered in the Phu Kradung Formation, a rock layer that also contains fossils of sharks, turtles, and other dinosaurs.1
Uragasaurus is the first officially named mamenchisaurid dinosaur from Thailand.1
